Scenarios about 'navigation'
The science and practice of determining position, course, and distance traveled across land, sea, or air. Navigation has evolved from celestial observation and dead reckoning to satellite-based systems, playing a crucial role in exploration, trade, military campaigns, and the development of global empires. In alternate history scenarios, different navigational technologies or their earlier/later development can dramatically alter patterns of exploration, colonization, and the balance of global power.
